[Tommixoft]

Description

TerminalApiSyncService returns timeout error when Message contains SaleToAcquirerData object.

Steps to reproduce

{
    var saleToPoiRequest = new SaleToPOIRequest
    {
        MessageHeader = new MessageHeader
        {
            MessageType = Adyen.Model.TerminalApi.MessageType.Request,
            MessageClass = MessageClassType.Service,
            MessageCategory = MessageCategoryType.Payment,
            SaleID = Reference,
            POIID = TerminalId,
            ServiceID = DateTime.Now.ToString("ddHHmmss")
        },
        MessagePayload = new Adyen.Model.TerminalApi.PaymentRequest
        {
            SaleData = new SaleData
            {
                SaleTransactionID = new TransactionIdentification
                {
                    TransactionID = MerchantReference,
                    TimeStamp = DateTime.Now
                },

                SaleToAcquirerData = new Adyen.Model.Terminal.SaleToAcquirerData()
                {
                    AdditionalData = new Dictionary<string, string> { { "authorisationType", "PreAuth" }, { "manualCapture", "true" } }
                },

                CustomerOrderID = MerchantReference
            },
            PaymentTransaction = new PaymentTransaction
            {
                AmountsReq = new AmountsReq
                {
                    Currency = "EUR",
                    RequestedAmount = Amount
                }
            }
        },
        SecurityTrailer = new ContentInformation()
    };
    return saleToPoiRequest;
} 

Actual behavior

Expected behavior

For some reason if i add SaleToAcquirerData to message i always receive adyen's http client timeout error. It can be AdditionalData, i also tried setting AuthorisationType and not creating AdditionalData - result are the same.
If removed SaleToAcquirerData from message body - all works.

            MessageCategory = MessageCategoryType.Payment,
